    Rated 5 out of 5 by from Exactly what I was looking for. I like having the gauges in a compact area, and the ability to change power settings on the fly. I haven’t really noticed an increase in mpg because I can’t keep my foot out of it long enough.

    Rated 4 out of 5 by from Works good Works great! Although overall happy, I'm extremely upset that this doesn't correct the cluster speedometer for bigger tires. It does display true speed through the edge but for the grand that I spent I would expect the gauge on the cluster to be corrected.

    Rated 2 out of 5 by from Great monitor Purchased this a couple weeks ago and other than the monitoring aspect, I haven't noticed much change in the overall performance. I run it on level 3 as a daily driver and it compares about the same as stock prior to the upgrade.

    I have a build LLY with a bigger turbo, egr delete, bigger exhaust, Will this system still work and tune it? Or is it only made for stock motors?

    Asked by: Jared 162838272728
    Edge doesn't offer any tuners that will delete the EGR or modify any of the emissions equipment.

    Is it normal for the tunes to not work until the engine is at a certain temperature?

    Asked by: Robertlly
    Yes with the Juice with Attitude it does have cold engine protection so it doesn't add full power until a certain ECT for more info give us a call at 888-360-3343.

    Do any of these tunes make an lly duramax smoke

    Asked by: Tyler1429
    We produce tunes to optimize fuel used for best performance. As some levels may smoke a little our goal is to eliminate smoke and use that unburnt fuel to increase optimal performance.
